Okay, maybe a couple of dollars if you add in labor for the 5 mins of work.
The last couple of days I have been trying out an idea. First test was for comfort. I wear dress pants to work, the kind that have the sewn in cotton back pockets. They are wide and deep, and are fairly well conceiled beneith the pants material itself. for the last couple of days I have been carrying a mag, beside my wallet in my left back pocket. It does fall over when I remove my wallet, but then this test was for comfert.
My G21 doublestack mag is about the same thickness as my (non George Constansia ) wallet. Last night I sewed a 2-1/2" single seam vertically in the pocket, making a divider. This is the part that would make blue jeans less likley to be used for this idea. I will have to play with it a bit to keep both the mag and Wallet easily removable, but it does work.
The seam starts about 1-1/2" below the top of the pocket, and does not have to go all the way down. It just needs to be long enough to keep the mag in it's vertical position with the wallet removed.
When I can get the %##$^ digital camera to talk to this &$%^$ computer, Pics will be posted.
Hopefully some here will find this useful.
